Abstract

It has long been a concrete technologist’s dream to discover method of making concrete at the lowest possible water/cement ratio while maintaining a high workability. To a considerable extent this dream has been fulfilled with the advent of super plasticizers. Have indeed added a new dimension to the application of admixtures with regards to production of high strength and flowing concretes. It is now possible to produce concrete with compressive strength of the order of 90Mpa (90 N/mm2). In the wake of energy conservation policy and diminishing supplies of high quality raw materials, there is a need to use marginal quality cements and aggregates for the production of concrete. In such instances the use of plasticizers/super plasticizers permits the production of concrete at low water/ cement ratios. Thus many waste materials of today become the useful by products of tomorrow. It is the particular role of plasticizers/super plasticizers, which is very importance for us here in Pakistan, because of our poor economy and less developed industrial base. Besides, the addition of plasticizers/super plasticizers to produces concrete with less cement but normal strength and workability is another application, which has received more attention. In this research programme one types of super plasticizer (Perma Plast) of polymer has been used. The water cement ratio was maintained as 0.40 &0.45 for OPC & PPC respectively. to study the effect of these PP on various properties of concrete. The dosage of plasticizers/super plasticizers was measured as 1.5% for perma plast for OPC & 1.3% for PPC by the weight of cement.
